IMPROVEMENT IN WATER-GASES FOVR STEAM-BOHILERS.

Speciication forming part of Letters Patent No. 194,796, dated September4, 1877; application iled March 29, 1877.

To all whom it ma/y concern:

Be it known that I, DANIEL A. WooD BURY, of the city of Rochester,county of Monroe, and State of New York, have invented a new and usefulImprovement in what are known as Gage-Columns for Steam- Boilers,7 whichimprovement is fully set forth in the following specification andaccompany* ing drawings, in which- Figure l is a front view in partsection, the portion shown in section being on a vertical line throughthe center. Fig2 is a crosssection on the lines c d and g h, Fig. l.Fig. 3 is a similar one'` on the line c f. Fig. 4 is a section on theline ij.

The object of my invention is to furnish a more compact devicecontaining the gagecocks and water-gage, in which all ofthe waterdischarged shall be concentrated at one point, from which it may beconveyed through a single pipe; also, in which all of the cocks usedshall be mutually interchangeable; also, to provide an attachment forthe steamgage which shall obviate the necessity of using what is knownas a siphon.77

In the drawings, A is the main chamber, communicating with the boiler,above and below the water-line, through the pipes B B, in the usualmanner.

The gage-pipe F, with its stufng-boxes K K, is supported by projectionsformed on the side of the chamber A, and communicating with it throughthe passages G Gr and cocks H H. These cocks are placed opposite thepipes B B, furnishing convenient openings through which these pipes maybe cleared when required.

C O are the gage-cocks, discharging through the opening a a into thecommon passage D, thence into the pipe E. Any suitable number, of cocksmay be used, all discharging into one common passage.

The passage D is provided with the external aperture b, through whichthe character of the discharge can be seen, it' necessary. The cock I isplaced below the gage-tube F, connecting with it through the passage G,and discharging into the passage J, thence into the pipe E. Through thiscock the sediment collecting in the gage may be blown out in the usualmanner.

The cocks shown are all of what is known as the compression form,7 butare so constructed as to iit steam-tight into the metal upon both sidesof passages into which they discharge. The construction is best shown inI, Figs. l and 4. Any other form of cock capable of being so iittedanddischarging in the manner described may be substituted.

The cocks used being all of one form and size greatly simplifies themanufacture, and an extra one, kept in reserve, will supply either placeshould one require renewing. This last feature is of great value whererepairs cannot be readily obtained. It also enables one much used, andconsequently more worn, to be exchanged with one less used.

Inside of the chamber A, and near its top, is formed the basin L, toretain water deposited by condensation. Thepipe M, leading to thesteam-gage, extends into and reaches nearly to the bottom of this basin,and the end is thus kept constantly immersed, thereby dispensing withthe siphon in general use. This pipe may be cast with and form a part ofthe chamber A, if desired. This basin, being made shallow, with slopingsides, has the further advantage of non-liability to injury in case offreezing.

The operation of the different parts will be readily understood withoutfurther description.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The gage-cocks C O, in combination with the passage D and chamber A,all constructed and operating substantially as shown and described, andfor the purpose specified.

2. The cock I, in combination. with the passage J and chamber A,substantially as shown and described.

3. The basin VL, in combination with the pipe M, substantially as shownand described.

D. A. WOODBURY.
